How to Spot Iceberg Orders When Trading
An Iceberg order is a large market order that hits the market. These typically come from large institutions. As technology improved institutions realized that other traders could utilize this information and trade off of it. If their technology was fast enough they could front run them by buying the stock before they did and selling it to the institution at a higher price. Because of front running institutions utilized algorithms to split their large orders into smaller ones.
